In one of the threads on these modules (here) around nine months to a year ago, I think the OP had figured out how to make the modules externally programmable.

Anyway, at some point the OP of that thread discoverd some glitch in the device which suddenly caused the voltage to become uncontrolled, and I think caused some kind of problem. I don't think this was in the standard use case, so it likely does not matter to viewers just looking for a power supply.

Also, this was a while ago so its entirely likely that whatever the glitch was the manufacturer may have fixed it.

I will try to find the exact link. This was when I was looking for a good power supply so I may have even bookmarked it.

So, if this glitch was fixed, these supplies may also be a good base for a project to build a programmable CV/CC supply.

That overshoot when relased from CC into resistor to CV with no load at 10V (last test) was only slight - perhaps it's because the module can't deliver more than 11something volts.I wonder what the overshoot looks like when set to 5V, for example - whether it jumps to maximal input voltage too.

I built my bench PSU around the DPS3012. I got a 36V 10A open frame power supply for $12 on eBay and put it in an old salvaged housing with a couple fans out of an old server. Total out of pocket was $37 and it has handled some pretty stout sustained loads.

So, I could in theory, make it into a mains plug in by building an unregulated power supply to supply the requirement for these modules? I think I have the parts to make a 36 volt (heavily filtered) DC at about 2-3 Amps.

As some of you have noticed, we’ve stopped taking new orders for the EEZ H24005. Because we intentionally didn’t include a large margin in our pricing, the cost of the current manufacturing run is essentially the price paid for each unit and there essentially won’t be any left over to sell outside of those already purchased. Parts have already been ordered and deposits already paid to our manufacturers, so we can no longer accommdate new orders in the current batch. However, we’ve been discussing making a second batch, so please subscribe to project updates if you’d like to be informed if/when a next batch becomes available.

The biggest flaw with these modules is the low side current measurement. You have to be careful if using these in parallel and /or using a non-floating DC PSU for power input. The return current may go the wrong path and skew the modules current measurement.

The ripple was surprisingly low in the DPS5005 module. This is measured with 12V input and 5v 5A output.

Going to build one, as second PSU next to my trusty Delta Elekronika. What do you think, will noise/ripple figures be better if the module is powered by a classic transformer , bridge rectifier and big cap? Or is it not worth the weight and size increase of the unit?
